Communication is key in any project  - yet, it’s especially critical during a penetration test.  Because pentests are a point in time event with a time constraint, it becomes even more important to communicate any findings, blockers, changes to the environment, and/or any other variables that may turn into a hurdle for testers. Additionally, since pentesting can affect applications, environments and the access to them negatively, the importance of communication is amplified. Thus, the timing of communication is crucial to the success of the test.
